In my fj40 my rear heater seems to get fairly warm in about 5-10 minutes which is fine, so i start it up 10 mintues before i leave for school. my frotn heater however only starts to get a little warm after say 30-45 minutes. is it worht my time to try to take it out, clean it, and put it back in or should i just buy one in good working order that is complete. also my heater is missing about al the levers and such so that gives me more reason to get a nice one. if i should replace does anybody have one. where can i get nice refurbished ones? thanks
